'Doing hymen reconstruction': an analysis of perceptions and experiences of Flemish gynaecologists.

BACKGROUND: Hymen reconstruction (HR) involves the restoration of the hymeneal membrane's gross anatomical integrity. Among the medical profession, hymen reconstruction receives particular attention and its necessity is debated because the surgery is not medically indicated, and often reveals conflicting social norms on virginity and marriageability between health professionals and their patients. The focus of this paper is not to address the many open questions that the ethics and politics around HR reveal, but rather aims at contributing to the much-needed empirical evidence. It presents findings of a study conducted in Belgium (Flanders region), among gynaecologists that aimed at assessing their knowledge, views, and experiences on hymen reconstruction. METHODS: A digital self-administered questionnaire-based survey was sent to Flemish gynaecologists and trainees in Flanders registered with the Flemish Society of Obstetrics and Gynaecology (VVOG). RESULTS: Hundred-and-nine questionnaires were completed. The majority of the respondents (73%) had requests to perform HR. Knowledge and technical skills about HR were considered to be sufficient (69%), even though HR does not seem to be integrated in medical curricula or post-graduate training. Most respondents (72%) would favour the publication of a guideline by their professional organisation. Few respondents discuss alternative options with the patient (19%) and half of the respondents reject to perform HR (49%). The majority of our respondents are against reimbursement of the surgery (70%). Not even half of our respondents believes that a patient is at risk of further violence (47%). 7% of the respondents mentioned complications, but the majority was able to perform a follow up consultation. CONCLUSIONS: The responses of this survey cannot be generalised to the entire population of gynaecologists in Flanders, but do provide insights in how gynaecologists confronted with HR are approaching such requests, and thus contributes to the empirical evidence. Our paper showed that many Flemish gynaecologist are likely to encounter requests for hymenoplasty, but that a majority would not perform the surgery. There seems to be a lack of guidance and debate in Flanders on the social and moral dimensions of HR, and a number of complexities were revealed when gynaecologists address HR that need further research.

Multiple HPV infections in female sex workers in Western Kenya: implications for prophylactic vaccines within this sub population.

BACKGROUND: Whilst the imputed role of High Risk (HR) HPV infection in the development of cervical lesions and cancer has been established, the high number of HPV genotypes that Female Sex workers (FSW) harbour warrants that the synergistic effects of potential HR (pHR) and HR HPV genotypes be elucidated to assess the potential impact of prophylactic vaccines. This population in Kenya also harbours a number of other vaginal infections and STIs, including bacterial vaginosis (BV), trichomonas vaginalis (TV) and candida spp. The aims of this cross-sectional analysis in Kenya are to explore the epidemiology of abnormal cytology and the pairing of pHR/HPV genotypes in HIV-negative and HIV-infected FSW. METHODS: A cross-sectional study design of 616 FSW from Western Kenya aged between 18 and 61 years during 2009-2015 using a peer recruitment sampling strategy. RESULTS: Of the 599 FSW who underwent cytological examination, 87 had abnormal cytology (14.5%; 95% CI: 12.0-17.6%). A combined prevalence of HPV16 and 18 (29.6%; 95% CI: 22.2-37.8%) was observed in abnormal cytology. HPV 53 and 51 were the most observed pairing in FSW with abnormal cytology. Significant adjusted associations were found between abnormal cytology and TV (aOR: 30; 95% CI: 14.1-62.9), multiple HR HPV (aOR: 3.7; 95% CI: 1.9-7.3), HPV 51 (aOR 3.7; 95% CI 1.6-8.6) and HPV 52 (aOR 6.1; 95% CI: 2.8-13.3). CONCLUSION: HPV 51 and 52 were independently associated with abnormal cervical cytology in both HIV negative/positive FSW. The strong association between TV and cervical dysplasia and the high percentage of FSW harbouring more than one STI underscore the need for enhanced STI management within the framework of cervical cancer prevention.

Associations Between Vaginal Infections and Potential High-risk and High-risk Human Papillomavirus Genotypes in Female Sex Workers in Western Kenya.

PURPOSE: Infection with and persistence of high-risk human papillomavirus (HR HPV) are the strongest risk factors for cervical cancer. Little is known about the prevalence and role of concurrent sexually transmitted infections (STIs) found in HPV-infected female sex workers (FSW) in Africa. This study purports to test our a priori hypotheses that STIs are associated with genotypes pertaining to the α-group species 9. The objectives were to determine the prevalence of bacterial vaginosis (BV), Trichomonas vaginalis, and Candida spp in FSW, the association between these STIs and the prevalence of any potential HR and HR HPV genotypes in FSWs. METHODS: A cross-sectional study design of 616 FSW from Western Kenya aged between 18 and 61 years during 2009-2015 using a peer recruitment sampling strategy. Inclusion criteria for the study entailed female sex and >18 years of age and having engaged in transactional sex in exchange for money, goods, services, or drugs in the last 3 months. Women were excluded if they were pregnant, <18 years of age, had a history of cervical dysplasia or cancer, had current abnormal bleeding, or had a hysterectomy. FINDINGS: Of the FSW, 33.3% had HIV and 57.7% harbored a potential HR and HR HPV genotype. The 2 most prevalent potential HR and HR genotypes were HPV 16 (16.10%) and HPV 59 (12.20%). BV was the most common infection (48.3%), followed by Trichomonas vaginalis (31.4%) and Candida spp (19.9%). A multivariate regression revealed significant associations with both α-group 9 and 6; BV and HPV 58 (adjusted odds ratio [aOR] = 2.3; 95% CI, 1.0-5.2; P = 0.05), Trichomonas vaginalis and HPV 31 and HPV 35 (aOR = 2.0; 95% CI, 1.0-3.8; P = 0.04 and aOR = 1.8; 95% CI, 1.0-3.3, P = 0.05 respectively); and between Candida spp and HPV 53 (aOR = 2.0; 95% CI, 1.1-4.0; P = 0.03) and 16 (aOR = 1.9; 95% CI, 1.1-3.3; P = 0.03). IMPLICATIONS: Snowball sampling may have inadvertently excluded FSW less likely to benefit from a social network. Significant associations between BV and HPV 58 and between Candida spp and HPV 16 and 53 suggest the need for sexually transmitted disease management within a cervical cancer prevention program. The probable synergistic effects of the vaginal microbiota should be elucidated, especially within this vulnerable population. Given the potential for FSW to transmit STIs, robust epidemiologic sampling methods are urgently required that account for the heterogeneity of the FSW population.
